A study of a missile designed to fly at low speed with its longitudinal axis aligned with the flight path

Description: An experimental investigation to explore the practicability of a low-speed missile designed to fly with its longitudinal axis pointing along the flight path.

Effect of Transverse Body Force on Channel Flow With Small Heat Addition

Description: Note presenting an analysis of the steady, compressible, inviscid channel flow to which heat is added at a cross-sectional plane and which is also subject to a transverse body force.
